Abstract

Objective: To describe the recovery of neurophysiological responses to perturbation of standing balance after stroke. Methods: Surface electromyography (EMG) from hip abductors and adductors and ground reaction forces (GRF) were measured in response to 20 sideways pushes applied to the pelvis by a linear motor. Each subject's data from pushes in each direction were averaged and the presence of a muscle EMG response was assessed visually. Subjects: Thirteen acute hemiplegic patients were tested as soon as they could stand after stroke (median six weeks) and serially during recovery. Results: Four patterns of hip muscle activity were seen: (1) no response at all, (2) no response in hemiparetic muscles but compensation by contralateral muscles, (3) an appropriate, if delayed, response in the hemiparetic abductor but not adductor muscles, and (4) a relatively normal pattern in both hemiparetic muscles. Nine of 13 patients showed a change in pattern of hip muscle activity during recovery. All patients who initially resisted the sideways pushes solely with muscles of the unaffected leg later regained use of the hemiparetic hip abductors Conclusions: The pattern of hip muscle activation changed towards normal during recovery from stroke in most patients. Use of compensatory strategies early after stroke in these subjects did not prevent return of normal patterns of muscle activation later.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The asymmetrical stance in hemiparesis may be necessary to compensate for muscle weakness, delayed muscle activation, synergistic-dependent activation patterns of muscles, and perceptual deficits.

    “This finding suggests that the asymmetrical stance in hemiparesis may be necessary to compensate for muscle weakness, 67,68 delayed muscle activation, 66,69 synergistic-dependent activation patterns of mus-cles, 70 and perceptual deficits.71,72”

  • Standing patients with stroke are more stable when they keep their postural control over the unaffected limb.

    “Kirker et al 66 found that standing patients with stroke are more stable when they keep their postural control over the unaffected limb.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
